Re: Lbolt resets - Ultrium drive on C1010 Ultra160 SCSI Card

After trying different SCSI cables, terminators, and both interfaces on the SCSI card, I tried a different Ultrium 230 that I had as a spare. So far, this drive has not suffered any SCSI errors. I am running a full backup as a test, but it has already written 5 Gigs to the drive - the previous one was suffering lbolt errors after only a few megs. Sorry to take up your time!

Hi Shawn,

Not a problem - we love challenges.
My $ is on the possibility the card was not seated properly. Try it in another system & if it's OK there, give some grief to your installing vendor.

Later,
Jeff

Re: Lbolt resets - Ultrium drive on C1010 Ultra160 SCSI Card

Hi Shawn,
Did you tried the same Ultrium Drive with the different SCSI card,cable & terminator inspite of trying with the spare Ultrium Drive??,I think there must be some connectivity problem maybe with the card,cable or terminator.

Shawn,
in addition - did you chek drive's firmware to be the latest? http://h18006.www1.hp.com/products/storageworks/ltt/index.html

Re: Lbolt resets - Ultrium drive on C1010 Ultra160 SCSI Card

I don't know why it ever worked.

The Ultrium 230e external drive is a self terminating drive. It does not need a terminator and does not work right when you terminate it.

Take a look at the back of the drive and see if the termination light is on. Then remove the terminator and check it again.

Perhaps the expanation for it working on the 11i box and not the A box running 11.00 is OS.

Re: Lbolt resets - Ultrium drive on C1010 Ultra160 SCSI Card

This drive has continued to be a problem, but I've simply used the working drive for the last year - unfortunately, the good drive has failed now and the other one still gives Lbolt errors continually.

I haven't got another LVM/SE add-in card to test it with, and HP tells me that the built-in LVM card will not work with this tape drive. It's an Ultrium 230M, not 230e. I've gone with the assumption that the drive itself is bad, since the other one was working with the same supporting hardware. The SCSI card was moved from one server to another during this time, and the bad drive has been consistent in giving lbolts throughout all attempts to test it.

The "good" tape drive's failure is mechanical, nothing to do with the SCSI interface. replacements for both drives are on the way.
